The filing period has concluded for most county, state and federal offices in Los Angeles County for the March 3 primary election, including the congressional seat vacated by Katie Hill.

Since the filing period for the full two-year term began Nov. 12, seven Democrats, five Republicans and two men with no party preference were issued papers to run in the 25th Congressional District, which includes Santa Clarita, Palmdale, Lancaster and the northern part of the San Fernando Valley.

Democrats seeking the seat include Assemblywoman Christy Smith (D-Santa Clarita), online news show host Cenk Uygur and documentary filmmaker Christopher Smith.

Former Rep. Steve Knight (R-Palmdale), whom Hill defeated in November 2018, filed papers on Nov. 5 to run for the seat.

Republicans filing earlier include Mike Garcia, a graduate of Saugus High School and the U.S. Naval Academy who was a Navy fighter pilot during the Iraq War and became an executive with the aerospace firm Raytheon Co.

George Papadopoulos, an aide with President Donald Trump’s 2016 campaign who pleaded guilty to making false statements to FBI agents, is another Republican who was issued paperwork to run for the seat, but, at press time, has not completed the process, according to the Los Angeles County Registrar-Recorder/County Clerk.

Filing for the special election to fill the remainder of the two-year term Hill was elected to in 2018 will begin Dec. 23 and end Jan. 9. The special election will be held March 3.

Hill, a Democrat from Santa Clarita, resigned Nov. 1 amid allegations of a relationship with a staff member and the online release of explicit photos.

The March 3 primary also includes races for district attorney and an open seat on the Board of Supervisors.

Former San Francisco District Attorney George Gascon has returned to Los Angeles County to challenge District Attorney Jackie Lacey, who is seeking a third term.

Also challenging Lacey are Richard Ceballos, a deputy district attorney with the Organized Crime Division and Hate Crimes Unit, and Rachel Rossi, who has worked in the Federal Public Defender’s Office in Los Angeles, the Los Angeles County Public Defender’s Office and the county’s Alternate Public Defender office.
